Test Equipment

The RCA Abrasion Wear Tester is used to test surfaces for resistance to abrasion and wear. Typically used on painted or plated organic finishes, foil, and inked key pad lettering. This tester is widely used as a standard for many silicone key pad and membrane switch manufacturers. This abrader is used as a standard to the auto, appliance, cell phone, plastics, and coating industries. It uses an inexpensive roll of throw away abrasion paper. All build-up error is eliminated and consistent readings are easily obtained.

Our finger probe tester and simulator is a unique contact tester designed to press and depress switches, buttons, keypads, and membrane switches. This tester can be used for contact testing as well as general mechanical and cosmetic button wear. It uses a silicone finger test probe which conforms to ASTM 1578 and ASTM 1597 Fig. 1 Test Probe Option. Optional Finger Probe ASTM1597 and ASTM Fig. 2 is available in a variety of mounting thread options.

Built on a combination of the RCA Abrader design, and the Finger Pressing design of the Pneumatic Finger Tester, this Wet Abrader adds the ability to apply a liquid to a special NTI Abrasive Media. This abrasive media is then pressed and rubbed against the specimen using a silicone finger probe. The test probe conforms to ASTM 1578 and ASTM 1597 Fig. 1.

This product line of testers is designed to provide a wide range of finger pressing and/or sliding / rubbing motions to be used for contact and life cycle button testing, as well as to test for wear and durability. These machines can test all types of buttons and switches, as well as monitors, screens, displays, and really anything that may get wear from human fingers or other similar types of rubbing, pushing or sliding. One recent customer, a major international guitar string manufacturer, is using the MPT-2 to test the durability of their strings! Other types of testing is for products like membrane switches, silicone keypads, computer keys, buttons, or any item that is repeatedly pressed, rubbed or in contact with human fingers or a similar material or surface. The MPT-1 is a Single Axis tester and the MPT-2 (shown here) is a 2-Axis tester, which allows for simulating both a finger push and a slide at the same time.
